Publication number: 20240041446Abstract: A length or strand of resilient material is formed into a continuous ring having multiple tissue-engaging portions for engaging and spreading eyeball tissue segments apart. The strand is formed with elongated straight sides joined by corner portions which are enlarged in directions transverse to the length dimension of each adjacent side. The corner portions constitute the tissue-engaging portions and have top and bottom sections and a connecting section that forms a gap for receiving the tissue. Each side of the ring extends from a bottom section of one corner to a top section of an adjacent corner. When the ring is deployed, the tissue is captured in the gaps at the corners of the ring and also is engaged along each side as that side transitions from a position situated below the tissue to a position situated above the issue.Type: ApplicationFiled: October 23, 2023Publication date: February 8, 2024Inventors: Boris E. Malyugin, Vaclav Dusek

Publication number: 20230381018Abstract: A ring that can maintain a pupil in an extended position during an ophthalmic procedure. The ring has a plurality of loops that capture iris tissue. The ring is configured to extend the pupil when iris tissue is inserted into each loop. An ophthalmic procedure such as phacoemulsification can then be performed on the patient. The ring has a center opening that provides a wide view of the ocular chamber during the procedure.Type: ApplicationFiled: March 9, 2023Publication date: November 30, 2023Inventors: Boris Malyugin, Vaclav Dusek, Lawrence Laks

Patent number: 11602456Abstract: A method of implanting a continuous iris-expanding ring in an eye involves ejecting the continuous iris-expanding ring from a distal end of a cannula toward an iris of the eye, securing a distal portion of the continuous iris-expanding ring device ring to the iris of the eye, and securing a proximal portion of the continuous iris-expanding ring to the iris of the eye. The continuous iris-expanding ring is in a collapsed configuration in the cannula prior to being ejected and in an expanded configuration when the proximal portion and the distal portion of the continuous iris-expanding ring are secured to the iris of the eye and extend across the pupil.Type: GrantFiled: January 17, 2020Date of Patent: March 14, 2023Assignee: MicroSurgical Technology, Inc.Inventors: Boris Malyugin, Vaclav Dusek, Lawrence Laks
